Probiotik merupakan mikroorganisme hidup yang memberikan efek baikrnpada organisme lain atau inangnya. Penelitian ini bertujuan untuk mengetahuirnpengaruh pemberian probiotik jenis berbeda terhadap parameter kualitas airrnyang meliputi parameter fisika (suhu dan kecerahan), kimia (pH dan DO), danrnbiologi (jenis bakteri, jumlah koloni heteroftof dan keberadaan bakteri patogen).rnMetode analisis yang digunakan yaitu analisis parameter fisika dan kimia dirnlapang, dan analisis parameter biologi dilakukuan uji lab. Data yang didapatrndiolah menggunakan excel dan uji anova di spss. Hasil Pengecekan suhurnselama penelitian pada kolam profish, EM4 dan kontrol mendapati nilai berturutrnturut 27,3°-28,3ºc, 27,1 ºc-27,3 ºc 27,3 ºc-28,3 ºc. Nilai kecerahan yangrndidapati pada kolam profish, EM4 dan kontrol mendapati nilai berturut turut 27-rn28,5cm, 27-28,5cm, 26-28cm. Nilai pH yang didapati pada kolam profish, EM4rndan kontrol 7-7,7, 7-7,75, 7-7,73. Nilai DO yang didapati pada kolam kolamrnprofish, EM4 dan kontrol mendapati nilai berturut turut 3,7-5,2mg/l, 3,6- 5,5mg/l,rn3,7-4,2mg/l. Hasil Identifikasi jenis bakteri dan jumlah koloni yang paling banyakrnterdapat pada kolam profish. Hasil jumlah kolonibakteri heteroftof yang baikrnterdapat pada kolam profish. Hasil penelitian dapat diketahui tidak terdeteksirnadanya bakteri patogen (Escherichia coli) dengan warna khas hijau metalikrnpada sampel air di kolam pendederan ikan lele.rnKata kunci: Probiotik, Parameter kualitas air, Pendederan, Ikan lele sangkuriangrn(clarias sp).rnA


Deskripsi Lain

Probiotics are live microorganisms that have beneficial effects on otherrnorganisms their host. This study aims to determine the effect of differentrntypes of probiotics on water quality parameters which include physicalrnparameters (temperature and brightness), chemical (pH and DO), and biologyrn(type of bacteria, number of heterotrophic colonies and presence of pathogenicrnbacteria). The analytical method used was the analysis of physical andrnchemical parameters in the field, and the analysis of biological parameters wasrncarried out in a laboratory test. The data obtained was processed using excelrnand the ANOVA test in SPSS. Results Checking temperature during the studyrnin profish ponds, EM4 and controls found successive values of 27.3°-28.3°c,rn27.1°c-27.3°c, 27.3°c-28.3°c. The brightness values found in profish, EM4 andrncontrol ponds found successive values of 27-28.5cm, 27-28.5cm, 26-28cm.rnThe pH values found in profish, EM4 and control ponds were 7-7.7, 7-7.75, 7-rn7.73. The DO values found in profish ponds, EM4 and controls foundrnsuccessive values of 3.7-5.2 mg/l, 3.6-5.5 mg/l, 3.7-4.2 mg/l. ResultsrnIdentification of the types of bacteria and the number of colonies that are mostrncommonly found in profish ponds. The results of a good number ofrnheterotrophic colonies were found in profish ponds. The results showed that nornpathogenic bacteria (Escherichia coli) with a distinctive metallic green colorrnwere detected in the water samples in the catfish nursery ponds.rnKeywords: Probiotics, Water quality parameters, Nursery, Sangkuriang catfishrn(clarias sp)
